In the U.S. citizens still reeling from the Great Depression found the war, ironically, to be an agent through which the economy and industrial sector could bounce back, get back on its feet and charge into the future. Automobile manufacturers began building tanks, aircraft and other military vehicles while other public sector factories created ammunition, rations and other military gear such as fatigues and rifles.
So, to allocate materials and regulate production of these products, as well as items such as fuel, Franklin D. Roosevelt commissioned, through executive order, the War Production Board in January 1942.
And the War Production Board did just that - it raised production, lowered and, eventually, prohibited nonessential productions and created a priority scheme that dictated the distribution of services and materials. Metals, rubber, plastic, gasoline, oils, and so on and so forth were rationed by the board.
The board was disbanded in 1945 following the defeat of the Japanese Imperial Army. Yet throughout its four year lifespan, the board produced some $185 billion in military supplies, both in ordnance and logistical supplies such as medicine, gasoline and fatigues.
Yet production and allocation were not the sole inhibitors and allocators in the economy of World War II America. Price control also played a pivotal role. Almost five months prior, in August 1941, the Office of Price Administration opened its doors in an attempt to control prices following the outbreak of the war. This administration was also brought into being via executive order.
"Besides controlling prices, the OPA was also empowered to ration scarce consumer goods in wartime. Tires, automobiles, sugar, gasoline, fuel oil, coffee, meats, and processed foods were ultimately rationed," (Encyclopedia.com). Moreover, the OPA had the ability to instate price ceilings and at the peak of the war some 90% of food stuffs were frozen under rationing - the Office often authorized subsidies for commodity production.
The OPA and all of its affiliates, such as the transference of its abilities to the Office of Temporary Controls, was abolished in 1947. Sections of its control were transferred to differing agencies such as the Department of Agriculture and Reconstruction Finance Corporation for a limited time.
But ultimately, organizations such as the OPA and WPB brought the United States, through WWII, out from the grip of the Great Depression. Increased wartime production brought many jobs to the exorbitant amount of unemployed, kicked started the economy and brought a huge and, as of then, highly unexploited asset to the forefront - women workers: Rosie the Riveter. And, in hindsight, the rationing aided the troops serving in the European and Pacific theaters much needed supplies and morale.
Here, another agency, the War Manpower Commission, a commission created to bring workers into the production force, one directly related to how and through what means the OPA and WPB functioned, is explained...
